Figure 3.

Converted σxx(B) and σxy(B) at various T ranging from 0.3 to 1.5 K. For (a)Vg = −0.125 V, (b)Vg = −0.145 V, and (c)Vg = −0.165 V. The insets show σxy(B) at T = 0.3 K and T = 16 K together with the fits to Equation 3 as indicated by the red lines. The vertical
lines point out the crossings of σxx and σxy.
